Sewing Speed and Setting Up
of
Pulley (Figl)
The highest sewing speed is 6000r.p.m. and ordinary one is 4800r.p.m.
However, it is preferable to operate the new machine at 4,000r.p.m. in about 200 hours, after which at 4800
r.p.m. ordinary speed. This manner will help life fo machine to be much longer.
Turning direction
of
pulley (A) is clockwise as well as handwheel (B), which is
sho\\11
in (Fig 2).

The machine should use clutch motor
of
one or three phase,bipolar,400W and v belt
of
type
"Z".

To
position the motor, make both Center lines
of
motor pulley and
machine pulley be aligned when motor pulley is shifted to left side
while pedaling.
After fixing
of
motor
in
correct position, fit on belt guard cover. (Fig 3)

Because oil will have been drained completely from machine at shipment, it must be filled in reservoir up to
upper line
of
oil gauge(C). (Fig 4, Fig

5-3 Oil Sight Gauge
and
Check
Procedure
of
Oil Cycling.
Check Oil sight gauge everyday before operation and replenish oil
if
its face is below underline
of
the gauge.
Looking through Oil sight top nozzle before operation, observe the flowing
of
oil (Fig.4)
5-4 Exchange
of
Oil
To
keep the machine longer life, oil should be changed completely after the initial use around 200 hours, then
change oil 2 or 3
times
yearly, Change
of
oil shall be made according
to
the following order (see Fig 6)
a.
Remove v belt from motor pulley, then remove machine head from
supporting board
b.
Remove belt guard
c.
Remove drain screw (D) and drain oil
d.
Retighten screw (D) correctly
e.
As
for
replenishment
of
oil, refer
to
"Feeding
of
Oil"
5-5 Cleaning
of
Filter
and
Screen
When the filter
is
blocked up, the oil supply will
be
affected. Usually, it
should be cleaned 2 or 3 times yearly. Some-times, although there
is
sufficient
oil in oil reservoir, no oil could
be
spreaded form the nozzle
In
t he case, the
operator should turn off the machine immediately, clean or exchange the filter.
Whenever oil feeding or exchanging
of
oil, cleaning
of
filter, care must be taken,
not
to
contaminate V belt and timing belt inside the machine.
As
for
the remove
procedure
of
oil
filter,
refer
to
Fig 7

Needle to
Be
Used,
Fitting
Of
Needle
and
(1)
and
(2) Device
r-------------~
The machine uses needles
of
Model UY 128 GAS. There are many sizes
of
needles.
So
that suitable size
to
the
nature
of
sewing materials must
be
selected. Generally, needle
of
#65-75
is
the standard size for light Weight,
mediumweight and medium heavy fabrics and #90
for
heavy duty.

--.
Needles should
be
set correctly facing their long slot to wards operator, mark
(x) in Fig 8 shows incorrect setting
of
needle.
While operating machine in high speed, due to the friction occurred between
needle and fabric causing stitch skipping, thread broken and the penetrated hole
on
the fabric will become much bigger, especially when compound thread and fabric
are used.

From the library of: Superior Sewing Machine & Supply LLC
To
prevent
from
occurring above case,
the
machine
is
equipped
standardized
(l)
device-for needle thread lubrication and (2) device-for needle
cooling (Fig.9)
To
achieve most efficient effect
of
these devices, silicon oil should be
used.
Generally,
we
suggest
to
use these devices
as
much
as
possible
and
often open
the
covers
of
them,
check
the oil amount
and
make feeding
of
silicon oil in
time.
Fig9
If
these devices are not necessary,
it's
better
for
you
to
take out
felt
from (1), (2) devices
and
not let
the
needle
tips
and
thread
to
touch
them

6-3 Operation
of
Spring-out Type Bobbin
Thread
Guide (Fig 22)
In
order
to
make
bobbin threading
easy,
the
machine designs
to
be
equipped with spring-out type bobbin thread
guide.
Lets
operation
procedure
is
as
follows:
(I)
Set
needle bar
to
the
highest position by turning hand
wheel.
(2)
Press
down
the thread guide lever
(B),
let
the
slide bracket(
C)
of
thread
guide
automatically spring out towards
the
separator.
(3) Guiding
the
thread through thread guide eyelet
(D).

Push
forward the slide bracket
(C)
of
bobbin thread guide, make it be locked and threading conectly, unless
the
good
balance
is
lost in the seaming.
6-4
Thread
Tension
Generally thread tension
is
decided
by
or according
to
kind
of
fabric,
thread and seamwidth
and
stitch length.
Therefore, thread tension should be adjusted
as
loosely
as
possible.
As
for
the detailed description, please refer
to
"Adjusting ofThread
Tension"
.

6-5 Pressure
of
Presser Foot
and
Its
adjustment
When pressure regulating
screw
(B)
is
turned clockwise, increase the pressure
of
presser foot, otherwise
decrease it, In perfect feeding
ofpoor
stitch will
be
caused
if
the pressure
of
presser foot
is
not
set
properly .so that
care
be
taken while adjusting,
to
keep the pressure
of
presser foot as weakly as possible under the condition that
stitch
is
unifonn,
if
the needle doesn't drop into the center
of
dropping space as the illustration shows,
it
is
necessary
to make adjustment Firstly, to loosen
screw
(1), and move presser foot (2), to assure the needle drop correctly .Then
tighten screw
(I)
again. (Fig 12)

of
the Differential Feed Ratio
The differential Feed Ratio
of
this machine is adjustable from 1:0.5 to
1:

To
adjust the ratio, loosen the
nut
(2), move the indicator (

Tension
of
Needle
Thread
(Fig. 16,18)
The distance between needle thread take-up (A) and center
of
fixing
screw
(B) is 75nnn,
When
needle lever
is
at
its
highest position,
This
is
the
standard position
of
the needle thread take-up. After loosen screw (B), move the
needle thread take-up towards (Y) direction, tighten needle thread; move
it
towards (X) direction, loose needle
thread.
If
needle thread tension could
not
be
regulated through above procedure. You'd better loosen screw (C), move
"D" device towards (Y)
or
(X) direction, and
see
if
the tension
is
satisfied. Generally, move it towards (Y) direction,
tighten the needle thread, move it towards (X) direction, loosen the needle thread. (Fig 18)
.----------------.
Bmmcf(]
Fig18
In
case
of
general sewing condition, the distance between the center
of
screw
and thread eyelet
of
thread guide
should
be
8rrnn
Sometimes, owing to the different kind
of
thread nature, it
is
hard to form thread loop, causing skip
of
stitch, it's
better for
you
to press the needle thread under needle clamp thread pressing plate. Sometimes, the thread loop
ofleft
needle
is
formed too big,
it
can
also
be
pressed under the needle clamp pressingplate. (Fig. 19)
7-2 Adjusting ofNeedle
Thread
Retainer
Device (Fig. 19)
In case
of
stretchable thread
such
as synthetic thread is used, needle thread loop will
be
unsteadiable,
at
this
moment, needle thread retainer device (F)
can
be
used
To
adjust the retainer device,
when
needle
bar
is
at
its lowest position,
let
the eye
of
eyelet (E)
be
even with the
surface
of
thread retainer device (F).
Make the retainer (F) up
or
down
by
loosening screw.

To
adjust, loosen Screw (3) and (4), and move the Spreader Thread Take-up (2)
up
or down, and then tighten
screw again. (Fig 20)
7-4 Adjusting ofTension
of
looper
Thread
The standard positioning
is
that eyes
of
eyelet
F,
G,
and mark "0" on cast
off
supporting plate are aligned
To
get plenty
of
casting thread, loosen fixing screw
of
eyelets (F) and (G) move them towards direction (L), otherwise move them towards
direction (S) and retighten the fixing screws in
time
(Fig 21).
Please pay attention to that, too much plenty
of
casting thread will cause skip
of
stitch. In case
of
woly thread used, thread eyelets (F) and (G) must be set fully
towards direction (L) and thread should not be pressed under small thread pressing
plate (H) (Fig 21)
7-5 Positioning ofLooper
Thread
Take-up
The illustration shows thread take-up seen from side
of
needle bar. Lower the needle bar from
the
highest
position by mining hand wheel. When the needle
bar
is
at the half position
of
looper, loosen screw (J), and move
looper thread take-up, let the looper thread cast
off
from the top
of
looper take-up cam
1,
then retighten screw
(J).little later. (Fig
